SuperGalum for Band
Characteristics

• Excellent heat resistance

Level of oxidation with continuous heating
Heat resistance
? Extensive use at temperatures of around 315? or
less causes very little change in ALCOT and does
not affect its attractive surface
brightness. ? Maintain surface attractiveness at
extensive temperatures up to 315? the surface
color changes slowly from grey to black at higher
temperature.
